The first quasars were discovered with radio telescopes in the late 1950s. However many were recorded only as radio sources with no visible object. Hundreds of these objects were recorded by 1960 and published in the Third Cambridge Catalogue. In 1960, a radio source was finally tied to an optical object. Astronomers detected what appeared to be a faint blue star at the location of the radio source. In 1962 another radio source, 3C 273,measured by Cyril Hazard and John Bolton during one of the occultations which allowed Maarten Schmidt to optically identify the object and obtain an optical spectrum. This discovery revolutionized quasar observation. The term quasar was coined by astrophysicist Hong Yee Chiu in 1964.

The first quasar was discovered on August 5th, 1962.

The first quasar discovered was on August 5th, 1962.
There probably was many before this though.
Because quasars was discovered to be a strong source of radio waves.... --> Hi Armstrong SY 2011 - 2012 of MunSci!! Goodluck on your street dance and book nook!!
Quasars still exist.
No. Quasars are at the centers of distant galaxies.
All quasars are located at a great distance from us. Of the quasars discovered, they range from between 780 million and 28 billion light years away. Because of these distances and the velocity of light, we are seeing them early on in the creation of the Universe. They are very rare they have only found about 20 or so.

Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
The first quasars were discovered in the 1950's
pulsar and quasars
None of them. They were all discovered a good many years ago.

The word quasar refers to a quasi-stellar radio source. Quasars are astronomical bodies that produce vast amounts of energy. The first Quasars have been discovered in the late 1950s.
Yes. Several quasars have been discovered; they are black holes, and they are quite active.
Quasars still exist.

Quasars are thought to be distant super-massive black holes.
